The following is excerpted from the Lisp Frequently-Asked Questions document
(FAQ), available by anonymous ftp from ftp.think.com:/public/think/lisp/faq.text,
among other places. It is also posted monthly to the comp.lang.lisp newsgroup,
and is constantly updated with fresh information.

[4-1] Where can I get an implementation of Prolog in Lisp?
Implementations of Prolog in Lisp:
The Frolic package from the University of Utah is written in Common Lisp
and available by anonymous ftp from cs.utah.edu:pub/frolic.tar.Z
Prolog in Scheme is a Prolog interpreter available from the
University of Calgary. It is written in Scheme and has support for
delayed goals and interval arithmetic. It is known to run in Chez
Scheme and in Elk, and is intended to be portable to other Scheme
implementations. It relies on continuations, and so is not easily
ported to Common Lisp. Available by anonymous ftp from
fsa.cpsc.ucalgary.ca:pub/prolog1.2/prolog12.tar.Z
Questions and comments may be addressed to Alan Dewar
<dewar@cpsc.ucalgary.ca> or John Cleary <cleary@cpsc.ucalgary.ca>.
An implementation of prolog for Chez Scheme is available by anonymous
ftp from titan.rice.edu:public/slog.sh. It is a collection of macros
that expand syntax for clauses, elations, and so on into pure Scheme.
It should be easily portable to other Schemes. Its use of
higher-order continuations is probably a major obstacle to porting it
to Common Lisp. For more information, please contact the author:
dorai@cs.rice.edu.
LM-PROLOG by Ken Kahn and Mats Carlsson is written in ZetaLisp and not
easily portable to Common Lisp. It is available by anonymous ftp from
sics.se:archives/lm-prolog.tar.Z.
Peter Norvig's book "Paradigms of AI Programming" includes Common Lisp
implementations of a prolog interpreter and compiler. The software is
available by anonymous ftp from unix.sri.com:pub/norvig and on disk in
Macintosh or DOS format from the publisher, Morgan Kaufmann. For more
information, contact: Morgan Kaufmann, Dept. P1, 2929 Campus Drive, Suite
260, San Mateo CA 94403, (800) 745-7323; FAX: (415) 578-0672
[note: Norvig's code is also on the MCL 2.0 CD-ROM]

Edinburgh-compatible Prolog integrated with Common Lisp. Write to:
